Yes. It's using two (or three) blocks. You have a block with your titleblock linework, a second block with just the global attributes (those that are the same on all sheets) and a third block with just the attributes unique to each sheet.
Or not. My organization uses one block for the TB, and that block contains all the attributes. Global attributes (like project name, tracking number) and the individual sheet attributes (sheet number, author). And that block lives in our drawing template, so any new drawing started with our production template automatically contains the titleblock and all its attributes. There is no need to go hunt it down and insert it later.
Either method works, it's just how much control you want over the information in your TB.
Sit down with your titleblock and work out what info you need, and whether that info is unique to a sheet, or is global across all sheets. Check it against all the available SSM fields, and map out the connections between SSM fields and your titleblock. And you can always revise it if you don't get it right the first time.
